[GNC] CSS GTK Register padding/spacing

[Ken Farley]

Don't know if you ever solved this, or if a solution is possible, but 
these are the lines from my GTK3 CSS file that deal with the register lines.

*.gnc-class-register-primary
{
   background-color: @hueRegLight ;
   color:            @hueTextNormal ;
}

*.gnc-class-register-secondary
{
   background-color: @hueRegDark ;
   color:            @hueTextNormal ;
}

I don't know if the padding values are available to change. You'd have 
to try it. First, make sure you are setting the register settings that 
are available by making the color something ridiculous like pink, to be 
sure your syntax is correct. You can always change it back to white or 
whatever you were using. I have variables set in my CSS file that I can 
reference in many setting statements, so if I want to change a setting 
for "normal text" everywhere, I only have to change it once, at the 
beginning of the file.
